An award-winning Indian documentary-maker sued New York City on Tuesday because police ordered him to stop filming in public in 2005 and held him for four hours, apparently suspecting he was plotting an attack. The New York Civil Liberties Union, acting as lawyers for filmmaker Rakesh Sharma, believes it is the first suit to challenge police restrictions on taking pictures in public in the wake of the September 11 attacks. Sharma has won numerous international film awards for the documentaries "Final Solution," on the killing of Muslims in the northwest Indian state of Gujarat in 2002 and 2003 and for "Aftershocks," on the 2001 earthquake in Kutch, Gujarat.
